Description
Spray or Drip Tips Having Multiple Outlet Channels FIELD OF THE INVENTION
[001] The present disclosure relates to drip or spray tip assemblies for use with devices that mix and apply two or more components. More particularly, the present disclosure relates to a tip assembly, wherein the tip automatically, semi-automatically, or manually changes to a fresh mixing chamber and it thus is capable of redirecting flow when clogging occurs.
BACKGROUND
[002] Drip or spray devices for dispensing two or more synthetic or biologies based sealant components are known. In the medical device field, such devices are typically used for applying bioadhesives, polymers and other synthetic materials used as wound closures.
Because of the reactant nature of the biocomponents used to form the bioadhesive blends, mixing of the components does not occur until the solution is ready to be applied. Mixing of the components too soon before application may result in premature hardening of the mixture, thereby making application of the solution impossible. Thus, in known spray or drip devices, the two or more components are maintained separately until just prior to application. The drip devices include one or more mixing means for mixing the two or more components prior to application. The mixing means may be passive, i.e., spiral configuration in the tubing, or instead may be active, i.e., mixing blade or impeller, with active mixing requiring more complex devices design. Once mixed, the solution may be applied through a needle-like output or may instead be ejected through a spray assembly. Thorough mixing of the two or more components prior to application is important to ensure that the solution will perform as intended.
[003] An exemplary device is taught in U. S. Pat. No. 5, 116,315, entitled "Biological Syringe System", which discloses a system for delivery two fluids in a mixed composition, comprising a manifold and a discharge assembly. The discharge assembly mixes fluids in a mixing space and then atomizes the mixed fluids in a spray delivered from the assembly. Similarly, the device shown in U. S. Pat. No. 5,605,255, entitled, "Apparatus for Spraying a mixture of Two Components", is an apparatus for spraying a liquid mixture having two syringes, a connecting piece, a premixing chamber, and a reduced volume section
downstream from premixing chamber, and an exit aperture for spraying the mixture. The reduced volume section terminates in a homogenization region. U. S. Pat. No. 6,063,055, entitled "Turbulence Mixing Head for a Tissue Sealant Applicator and Spray Head for Same", illustrates a device in which the mixing is performed in a mixing head.
[004] Intermittent use of a biologies spray device, as may be required during a procedure, tends to clog the outlet of the applicator tip. As a result, most applicator assemblies are provided with a number of replacement tips for use when clogging of the tip occurs.
Replacing clogged applicator tips interrupts the flow of a procedure, is time consuming and is an added expense. The device in published U. S. Publication 2010/0096481, "Self-Cleaning Spray Tip", is described as having the distal end of spray cap assembly with an outlet that changes its configuration~at rest and at a second condition (e.g. during expression). The distal end is described as comprised of a material that permits flexion and expansion. The first and second reactive components are introduced into swirl chambers before mixing and are atomized as ejected through the outlet in a cone-shaped spray
[005] U. S. Patent No. 5,605,541 "Fibrin sealant applicator" discloses a device for applying a fibrin sealant comprising two components which will form said sealant when combined, which device comprises commonly actuable reservoirs for each of said components and a source of gas, wherein each of said reservoirs and said gas in separate fluid communication via a discrete channel to a spray head, said spray head having a first aperture located centrally in an exit end of said spray head through which said gas is discharged, said spray head having a first annular aperture in the exit end of said spray head within first annular aperture is concentric with said first aperture and through which one of said fibrin-sealant-forming components is discharged, and a second annular aperture in the exit end of said spray head being concentric with said first aperture and concentric with, and having a radius larger than said first annular aperture through which the second of said fibrin-sealant-forming components is discharged wherein all of said apertures are in a common plane.
[006] U. S. Pat. No. 6,773,414 "Device and method for dispensing at least two mutually reactive components" discloses a device for dispensing at least two mutually reactive components, comprising a component supplier having primary channels for supplying respective ones of said at least two reactive components to a component dispenser having
secondary channels for separately discharging said at least two reactive components through orifices opening into a free target area at a distal tip end of the dispenser for external intimate mixing of the respective reactive components outside a distal tip end of said dispenser, wherein distributors are interposed between said primary and secondary channels for multiplying the number of each respective primary channel with at least a factor 2, adjacent ones of said orifices of said secondary channels being adjoined to said primary channels intended for supply of reactive components of different kind.
[007] U. S. Patent No. 7,018,357 "External mixer assembly" discloses a fluid delivery system for dispensing a multi component biological adhesive having at least a first component and a second component, the system comprising:
a housing configured to receive a plurality of reservoirs;
a discharge nozzle housing a conduit assembly having a plurality of conduits with a proximal end thereof in respective fluid communication with separate of said reservoirs, a distal end of said conduits defining at least two exit openings, wherein each of said plurality of reservoirs includes a sealable opening configured for being penetrated by a proximal end of a respective one of said plurality of conduits; and
a deflector assembly provided on said housing, said deflector assembly having a deflector plate substantially parallel with said at least two exit openings, said deflector plate displaced at a distance from a distal-most end of said housing and oriented to deflect said first and second components after exiting from said at least two exit openings.
[008] U. S. Pat. No. 8,616,468 "Spray applicator" discloses a spray assembly for dispensing a mixture, the assembly comprising: a connector configured for operable engagement with a first source of component and a second source of component; an elongated member operably connected to and extending distally from the connector, the elongated member including an inner shaft and an outer sleeve, and defining a vent lumen between the inner shaft and outer sleeve, the inner shaft defines at least a first lumen configured for fluid communication with the first source of component and a second lumen configured for fluid communication with the second source of component; a tip operably connected to the connector, the tip including an opening and defining a mixing chamber between a distal end of the elongated member and the opening of the tip; and an insert member configured to be received in the mixing chamber, the insert member defining at least one radially extending slot on a first end of the
insert member and at least one radially extending slot on a second end of the insert member, each of the radially extending slots being configured to mix the first and second components prior to the combination exiting the opening in the tip.
[009] There is a need in conveniently changing spray or drip tips to avoid procedure interruption if/when clogging of the tip occurs. Particularly in laparoscopic procedures, clogged tips may result in significant and undesirable delays in delivery of the sealant or hemostat.

DETAILED DESCRIPTION OF THE INVENTION
[0022] Referring now to Figure IB, an embodiment of a device 10 for mixing and expressing a multi-component sealant or hemostat or adhesive (or composition having one or more of these properties) is shown, comprising two or more containers or syringes 20 containing components of multi-part sealant or hemostat or adhesive, connected to a multilumen cannula 30 to which tip 100 having a plurality of exit ports 50 is attached.
[0023] Referring now to Figure 2, an embodiment of device 10 is shown in more detail, with syringe 21 containing a first component 22 and syringe 23 containing a second component 24, syringes 21 and 23 having optionally interconnected plungers 25 for simultaneous expression of components 22 and 24. Syringes 21 and 23 are connected to multilumen cannula 30 via connectors 28 and 29, so that first component 22 and second component 24 can advance in multilumen cannula 30 towards tip 100 through lumens 26, 27 without mixing, thus preventing clogging of the multilumen cannula 30. In the shown embodiment, multilumen cannula 30 is a dual lumen cannula. Multilumen cannula 30 can have an additional lumen for gas (not shown) for gas-assisted spray.
[0024] Elongated tip 100 has a proximal end 101 that is closer to syringes 21 and 23 and an opposing distal end 102 relative to syringes 21 and 23. Ports 51 , 52, from which the expression of the mixed liquid first component 22 and liquid second component 24 forming sealant or hemostat or adhesive are situated at distal end 102. Tip 100 has an axial main channel 1 10 open at proximal end 101 with cannula 30 configured to slidably fit into main channel 1 10 so that tip 100 is slidably moveable on cannula 30 and can advance distally when main channel 110 is pressurized due to clogging.
[0025] Tip 100 has a plurality (two are shown in the embodiment of Figure 2) of separate mixing chambers 121 , 122, open at distal end 102 of tip 100 to ports 51 , 52 respectively. Each of mixing chambers 121 , 122 are in fluid communication with main channel 110 via an individual connecting channel 131 , 132 respectively. Connecting channels 131 , 132 are open into main channel 1 10 at different distances from distal end 102, with distance of connecting channel 131 from distal end 102 Dl is indicated by arrow Dl and distance of connecting channel 132 from distal end 102 D2 is indicated by arrow D2. Distances Dl and D2 being
different by at least the width of connecting channels 131, 132 and preferably by more than the width of connecting channels.
[0026] In some embodiments, lumens 26, 27 of multilumen cannula have inside diameter of 0.2 - 2 mm, such as 0.3 mm, 0.5 mm, 0.7 mm, 1 mm, 1.5 mm. Outside diameter of multilumen cannula 30 is 0.5 - 10 mm, such as is 1 mm, 1.5 mm, 2 mm, 3 mm, 5 mm, 7 mm, 10 mm. Inside diameter of main channel 1 10 corresponds to outside diameter of multilumen cannula 30, i.e. 0.5 - 10 mm, such as close to or slightly larger than 1 mm, 1.5 mm, 2 mm, 3 mm, 5 mm, 7 mm, 10 mm. Inside diameter of mixing chambers 121 , 122 is 0.7- 3 mm, such as 1 mm, 1.5 mm, 2 mm, 3 mm. Inside width of connecting channels 131, 132 is 0.3- 3 mm, such as 0.5 mm, 0.7 mm, 1 mm, 1.5 mm, 2 mm. Distance Dl differs from distance D2 by more than width of connecting channels 131, 132 such as by 1.5-3 mm when diameter of connecting channels 131, 132 is 1 mm.
[0027] In some embodiments, two-part compositions comprise biological adhesive or sealant, forming fibrin glue, whereby first component 22 is fibrinogen and second component 24 is thrombin or thrombin analog or precursor. In other embodiments first component 22 is cross-linkable synthetic component, and second component 24 is a cross-linking agent.
[0028] Referring now to Figure 3, in operation with connected plungers, depressing plungers 25 results in simultaneous advancing first component 22 and second component 24 through lumens 26 and 27 of multilumen cannula 30 towards tip 100 without mixing. First component 22 and second component 24 then enter connecting channel 131 and first mixing chamber 121 , where first component 22 and second component 24 commingle and intermix to form a blend for sealant or hemostat or adhesive upon mixing. As shown by arrow A, the blend of first component 22 and second component 24 while undergoing additional mixing advance towards distal end 102 of tip 100 and exit tip 100 through port 51 toward targeted tissue, organ or wound (not shown). Exiting sealant or hemostat or adhesive formed through the blending and mixing of first component 22 and second component 24 can be expressed as a drip or as a spray, or combinations thereof.
[0029] The expression of sealant continues through port 51 as needed. Upon interruption of expression through port 51 , due to operational activities such as performing another procedure, repositioning or retargeting device 10, etc., clogging connecting channel 131 and
first mixing chamber 121 might occur due to gelling properties of the components. Such situation is shown in Figure 4, with clog 200 forming in first mixing chamber 121. As a result of clog 200 blocking exit of the mixture of first component 22 and second component 24 from device 10 via port 51 , upon health practitioner trying to restart expression and depressing plungers 25, pressure inside tip 100 increases. The pressure buildup is due to liquid components 22 and 24 having no path way for exiting tip 100 due to blockage by clog 200.
[0030] Referring now to Figure 5, where for simplification purposes, syringes 21 and 23 are not shown, increase in pressure results in sliding advancement of tip 100 distally, with tip 100 sliding on multilumen cannula 30 and opening a new portion of main channel 110 to the second connecting channel 132. The previous location of tip 100 corresponding to Figures 2- 4, is schematically indicated by dashed box 100a. The distal advancement of tip 100 as shown in Figure 5 opens a path for components 22 and 24 from main channel through connecting channel 132 and into second mixing chamber 122.
[0031] As shown by arrow "B", despite clot 200, first component 22 and second component 24 can exit multilumen cannula 30 by advancing through connecting channel 132 and second mixing chamber 122 to commingle and intermix and form a blend for sealant or hemostat or adhesive. Mixed first component 22 and second component 24 while undergoing further mixing advance towards distal end 102 of tip 100 and exit tip 100 through second port 52 toward targeted tissue, organ or wound (not shown).
[0032] As shown above, clogging of a first connecting channel 131, and/or mixing chamber 121 , and/or port 51 resulted in automatic change to second connecting channel 132, mixing chamber 122, and port 52. Advantageously, there is no need in manual tip 100 de-clogging, tip 100 replacement, or device 10 replacement during the treatment.
[0033] Embodiments described operate so as to switch to an unclogged mixing chamber automatically, meaning that the action occurred primarily as a result of internal pressure that caused a displacement and redirection of fluid flow. In another aspect, switching to an unclogged mixing chamber can be effected semi-automatically or manually. In semiautomatic operation, whereby practitioner manually advances and/or turns tip 100 to switch to second connecting channel 132, mixing chamber 122, and port 52.
[0034] Referring now to Figure 6, an embodiment of device 10 similar to embodiments shown in Figures 2-5 is presented, with tip 100 having four connecting channels 131, 132, 133, 134, in fluid communication with corresponding mixing chambers 121 , 122, 123, 124, terminating at distal end 102 in corresponding exit ports 51 , 52, 53, 54. Similarly to embodiments shown in Figures 2-5, upon clogging of first mixing chamber 121 and/or corresponding connecting channel 131 and/or corresponding port 51 , tip 100 automatically advances distally opening main channel 110 to second connecting channel 132 in fluid communication with corresponding mixing chamber 122, terminating at distal end 102 in corresponding exit port 52. Upon clogging of second mixing chamber 122 and/or corresponding connecting channel 132 and/or corresponding port 52, tip 100 further advances distally opening main channel 1 10 to third connecting channel 133 in fluid communication with corresponding mixing chamber 123, terminating at distal end 102 in corresponding exit port 53. Upon clogging of third mixing chamber 123 and/or corresponding connecting channel 133 and/or corresponding port 53, tip 100 further advances distally opening main channel 1 10 to fourth connecting channel 134 in fluid communication with corresponding mixing chamber 124, terminating at distal end 102 in corresponding exit port 54. While embodiment of Figure 6 shows four mixing chambers and exit ports, any number of such components can be incorporated into tip 100, e.g. three to ten mixing chambers and exit ports, such as five.
[0035] Spring 300 connecting tip 100 to structure 310 affixed below syringes 21 and 23 provides resistance to tip 100 moving distally and controlling tip motion in distal direction. Elements 129 shown in mixing chambers 121 -124 are optional static mixing elements or baffles facilitating intermixing of first component 22 and second component 24.
[0036] Referring now to Figures 7A-C, for simplification purposes, syringes 21 and 23 are not shown. In Figure 7 A, device 10 is shown with the expression proceeding through port 51. Upon formation of clog 210 as illustrated in Figure 7B, tip 100 advances by distance 60 distally and expression continues through port 52. Upon formation of clog 220 as illustrated in Figure 7C, tip 100 advances by distance 61 distally and expression continues through port 53.
[0037] Referring now to Figure 8, for simplification purposes, syringes 21 and 23 are not shown. Tip 100 is shown in a prospective view, mounted on multilumen cannula 30, with five ports 51 , 52, 53, 54, 55 providing expression outlets from tip 100.
[0038] Referring now to Figure 9, for simplification purposes, syringes 21 and 23 are not shown. Tip 100 is shown in a prospective cross-sectional view, mounted on multilumen cannula 30, with four ports 51 , 52, 53, 54 visible and in fluid communication with four mixing chambers 121 , 122, 123, 124 visible, having static mixers 129 in mixing chambers. Fifth mixing chamber and port are not visible in the cross-sectional view.
[0039] Referring now to Figure 10, for simplification purposes, syringes 21 and 23 are not shown. Tip 100 is shown in a frontal view, with five ports 51, 52, 53, 54, 55 visible.

wherein the tip contains a plurality of separate mixing chambers open at the distal end of the tip, each of the mixing chambers being in fluid communication with the main channel via an individual connecting channel at separate and distinct distances from the tip on the cannula; c) advancing the two components through separate lumens of the multi-lumen cannula without mixing to the tip; d) mixing the two components within a first mixing chamber; and e) expressing the components through a first opening at the distal end of the tip; f) upon clogging of the first mixing chamber, continuing to advance the two components through separate lumens of the multi-lumen cannula thus pressurizing the main channel; g) allowing the tip to slide on the cannula and advance distally to place a second mixing chamber in fluid communication with the main channel; h) mixing the two components within the second mixing chamber; and i) expressing the components through a second opening at the distal end of the tip.
12. The method of claim 1 1, wherein said mixing chambers each terminate at the distal end of the tip with a spray port or an atomizing spray nozzle.
13. The method of claim 1 1, wherein said mixing chambers each terminate at the distal end of the tip with a drip port or a drip nozzle.
14. The method of claim 1 1, wherein said mixing chambers contain at least one of static mixing element and wherein at least some of said mixing chambers terminate at the distal end of the tip with a drip port or a drip nozzle wherein at least some of said mixing chambers terminate at the distal end of the tip with a spray port or an atomizing spray nozzle.
15. The method of claim 1 1, wherein a spring is attached to the tip that resists distal tip movement and wherein the tip is configured to be manually advanced distally or turned to switch to another mixing chamber.
16. The method of claim 1 1, wherein the main channel is pressurized when the mixing
chamber is clogged by an at least partially reacted multi-component sealant.
17. The method of claim 1 1, wherein upon the tip advancing distally, a second connecting channel that is farther from the distal end of the tip than the first connecting channel is in fluid communication with the multi-component sealant.
18. The method of claim 1 1, wherein prior to dispensing any components, all but one
connecting channels are blocked by the cannula and are not in fluid communication with the main channel.
19. The method of claim 1 1, wherein the multi-component sealant or hemostat or adhesive upon reaction comprises a fibrin glue, wherein the first component of the multi- component sealant comprises fibrinogen or fibrinogen analog, and wherein the second component of the multi-component sealant comprises an agent that converts fibrinogen to fibrin, preferably thrombin of thrombin precursor.
20. The method of claim 1 1, wherein the multi-component sealant or hemostat or adhesive upon reaction comprises a synthetic polymeric material, wherein the first component of the multi-component sealant comprises a cross-linkable compound, and the second component of the multi-component sealant comprises a cross-linking agent.
